Wet-to-dry (W/D) weight ratio and dynamic compliance (CD). (a) W/D weight ratio was higher in the ventilator-induced lung injury (VILI) group than in the other groups (*P < 0.05), and the difference between all groups was significant (P = 0.001 by the Kruskal-Wallis test). (b) CD at the beginning of mechanical ventilation (MV) was similar among the lung-protective ventilation (LPV) (◆), VILI (■) and PJ34+VILI (▲) groups (P = 0.368 by the Kruskal-Wallis test). After 2 hours of MV, CD of the VILI group was lower than those of the other groups (*P < 0.05). CD of the PJ34+VILI group was higher than that of the VILI group (**P = 0.021) and lower than that of the LPV group (**P = 0.020) (P = 0.007 by the Kruskal-Wallis test among the three groups).
